Embodiment Construction

[0027] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0028] Such as figure 1 As shown, a dry magnetic separator includes a feed pipe 1, a conveyor belt, a belt scale 3, a vacuum cleaner 4, a magnetic wheel 5, a dust cover 6, a blower 8, an inflatable vibrating chute 9, a magnetic system 10, Pulley 14.

[0029] The conveyor belt is driven by the belt pulley 14 and the magnetic wheel 5. The conveyor belt is divided into a feeding section 2 and a magnetic separation section. The magnetic system 10 is set inside the magnetic selection section, and the magnetic wheel 5 is set on the inside of the corner where the feeding section 2 turns to the magnetic selection section. The magnetic selection section is along the direction of material flow. There are roughing section 15, arc-shaped refining section 11 and concentrate feeding section 16 in sequence, and an inflatable vibrating chute 9 is correspondingly ...

Abstract

The invention discloses a dry-type magnetic separator, which comprises a conveyer belt, wherein the conveyer belt is divided into a material conveying section and a magnetic separation section; a magnetic system is arranged on the inner side of the magnetic separation section; the magnetic separation section sequentially comprises a rough separation section, a circular arc fine separation section and a fine ore conveying section along a flow direction of materials; and an inflatable vibration inclined chute is formed below the rough separation section. The dry-type magnetic separator can continuously treat a large number of magnetic materials which are rolled by a high-pressure rolling mill and particularly separate high-level materials; and the subsequent process equipment is reduced, and the energy consumption of a process system is reduced, so that the materials can meet requirements of levels and yields after passing through the magnetic separator at one time.

Description

technical field [0001] The invention relates to a dry magnetic separator, which belongs to the field of magnetic separators used for magnetic material separation in metallurgy, mining and other industries. Background technique [0002] In the field of mineral processing in metallurgy, mining and other industries, it is necessary to select magnetic materials, such as iron ore. Now the industry is vigorously researching dry magnetic separators. Now public dry magnetic separators, the concentrate grade after beneficiation is often in a range such as 30%-60%, if only high-grade ore is required to be selected, these dry magnetic separators cannot achieve it; Especially after the roller press is applied to the crushing of magnetite, the material handling capacity is quite huge, and the commonly used dry magnetic separator cannot meet the requirements. [0003] The application number is 201010272770.3, the application date is August 31, 2010, the publication number is CN101972700A...
